BACtrack Trace Breathalyzer | Professional-Grade Accuracy | . & NHTSA Compliant | Portable Breath Alcohol Tester for Personal & Professional Use

The accuracy is excellent. I love having a product that helps maintain a responsible lifestyle. I bought this as an experiment (I work in a bar) to test the tolerance verses the person's accurate BAC. The results are very eye opening. Most drinkers have no idea how intoxicated their bodies are because of the tolerance they've built and so they feel functional and sober. Amazing product. I love it.

Bought this breathalyzer to replace one that broke. This one is a convenient size, accurate and reasonably priced. We'd sent our old one to this company for re calibration. Since it was broken, they applied the re calibration fee to the purchase of the new one. Fast , reliable service.

I bought two of these, one for my wife and one for myself, and we have been very pleased with them so far. The inverted LED screen is great, and the overall quality seems very good. I compared results across the two devices and got the exact same reading, which is reassuring of their accuracy. I do wish, though, that there was an easy way to know for sure when the device needs to be sent in for recalibration. But overall, I've been really happy with the Trace and would recommend it to anyone.

I bought the trace and a friend of mine has the S80. We took the two on a college spring break trip and would test the two against one another and on multiple people. They gave consistent results with one another and each reading seemed on par with how much alcohol each person had consumed. I definitely recommend this product.

What I like most about this product is how easy it is to use. I can now go out and drink and know exactly when the alcohol is out of my system and safe to drive

Great apparatus. I use it wisely to determine a responsible range to drive after a couple of drinks. You can find your baseline by experimenting at home so you know how alcohol interacts in your body using this device.

I have a friend who is a County Police Officer and I tested by BACtrack against his "official device" and the numbers matched perfectly EVERY time! You will absolutely know what your BAC is for certain - anytime, anywhere.

This apparently needs to be recalibrated. I have used it less than 300 times an it shows a different BAC than another monitor I purchased from your company.

This product looks and feels great. Then it stops working. I get a false reading on the batteries ALL THE TIME. Popping the back off and flipping the batteries usually works but who wants to do that? The memory button NEVER worked. Sometimes I fell like I have to blow for ten seconds and then it takes almost a minute, sometimes, to process. It seems cool to show off to your friends but I would NOT trust is. Just think, if the battery sensor does not even work, why would the alcohol sensor?

Bought it 3 weeks ago worked the 1st time i used it, has not worked since i will send it back for another one to try. If it works properly i will write a positive review.
